The gang is at Monica's place, and Chandler is heading off to Tulsa where he's staying for Christmas and New year, the gang are really disappointed.
Over in Tulsa no-one likes working in the holiday season. Chandler's secretary, Wendy, steals stuff from the downstairs party. Wendy asks him what he would be doing right now if he was at home and he has flashbacks to Christmas in New York - Phoebe singing her holiday song, looking for Monica's present with Phoebe and Rachel, the time when he and Joey get everyone presents from the gas station and the holiday armadillo. After these flashbacks, Chandler lets everyone go and accidentally tells them about working New Years Eve.
The gang call to wish him Merry Christmas and Chandler lets it slip that its only him and Wendy, which Monica is suspicious of. When he puts the phone down, Wendy makes a move on him. Then, Chandler has flashbacks about him and Monica - London when they start their relationship, at the hospital in the one hundredth where they're talking, when they are going to get married in Vegas and when they are talking about their wedding.
Over in New York, the gang are opening presents when they realize that it's snowing. Just then, Chandler walks in and announces that he quit.
Later, Monica realizes she is the sole wage earner and Chandler is very pleased.
